SASH LOCK AND SUPPORT.

Specification of Letters Patent.

Patented April 2, 1907.

Application filed May 21,1906. Serial No. 318,020.

To all whom it may concern.-

Be it known that I, DORA E. BARNES, a citizen of the United-States, residing at Hays, in the county of Ellis and State of Kansas, have invented a new and useful Sash Lock and Support, of which the following is a specification.

This invention relates to improvements in sash locks and holders, and has for one of its objects to produce a simply-constructed device of this class arranged to impart its force transversely of the window-frame or between the sashes and the stops to maintain the sides of the sashes pressed against the stops or other parts of the frame, and thus exclude the air and prevent rattling.

Another object of the invention is to provide a simply-constructed device with two reversely-disposed cams movable toward each other when they are to be released, so that when one of said cams is actuated the sash is movable in one direction and movable in the opposite direction when the other cam is actuated.

lNith these and other objects in View, which will appear as the nature of the invention is better understood, the invention consists in certain novel features of construction, as hereafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which corresponding parts are denoted by like designating characters, is illustrated the preferred form of the embodiment of the invention capable of carrying the same into practical operation.

In the drawings, Figure 1 is a view of a portion of a Window-frame and portions of the upper and lower sashes with the improved locking and holding devices applied. Fig. 2 is a section, enlarged, on the line 2 2 of Fig. 1. Fig. 3 is a perspective view of the locking mechanism for the lower sash, detached, and with a portion of the casing broken away. Fig. 4 is a perspective view of one of the cam members of the locking mechanism of the upper sash. Fig. 5 is a view of the blank from which the casing of the locking mechanism is constructed. Fig.

6 is a detail, partly in section, illustrating a modification in the construction. Fig. 7 is a perspective view of one of the cam members employed in the modified structure illustrated in Fig. 6. Fig. 8 is a view of a portion of one of the sash members with another modified construction arranged therein.

The improved device comprises a casing or frame adapted to be embedded in the sashes and two reversely-arranged locking members preferably in cam shape and movably disposed in said casings and operating, respectively, against the inside stop and the parting-stop of the window-frame, so that the sashes are compressed, respectively, against the parting-stop and the outside stop or outside casing, as the case may be, and according to the construction of the Window-frame.

In Figs. 1, 2, 3 the casing (represented as a whole at 10) is shown constructed of sheet metal and bent into the required shape, the blank from which the casing is constructed being shown in Fig. 5. The sheet of metal is first cut in rectangular shape and two U-shaped clefts of unequal size formed therein, as represented at 11 12, with the smaller cleft within the larger. released by the larger cleft 11 is then bent at right angles to the body of the plate along the lines indicated at 13 14, leaving the portion released by the smaller cleft 12 extending like a tongue across the aperture formed by the bending action. The plate is then again bent at right angles along the lines 15 16. Screw-apertures 17 18 are formed in the body of the plate, and spaced apertures 19 20 and 21 22 also formed, respectively, in the body of the plate and the bent portion re leased by the cleft 12. One of the casings thus constructed is embedded in the lower sash, a portion of which is represented at 23, and the other casing embedded in the upper sash 24, preferably near the top, as shown in Fig. 1, and around the corners of the sashes, as illustrated in Fig. 2.

The casings 10 are precisely alike and are secured in position upon the sashes by screws 25 26, fitting through the apertures 17 18, and are thus disposed in the rear of the inside stop 27 and the parting-stop 28, respectively, as shown.

The locking members are formed, respectively, with spaced sides 29 30 and 31 32 and connected by transverse webs 33 34, the sides swinging, respectively, upon pins 35 36, extending through the casing 10.

The sides 29 30 are formed at their free ends with serrated cam-faces 37 38, reversely arranged and bearing, respectively, against the rear sides of the stops 27 28, and thus exerting their force to maintain the lower sash compressed against the parting-stop 28 and the upper sash compressed against the out- The portion.

side casing or outside stop, according to the construction of the window-frame.

The transverse webs 33 34 are provided with inwardly-projecting ribs, one of which is represented at 39.

A spring extends between the pins 35 36 and is coiled around the same and with the terminals extended for bearing against the ribs 39, and thus exerting their force to maintain the locking members yieldably in distended position. The cam-faces 37 38 are thus movable toward each other to effect their release.

The sides 31 32 of the locking members are extended into operating-arms 55 41, and these arms may project outwardly from the lower sash and alongside of the stop 27; but the arms of the locking device of the upper sash are bent laterally and extended rela tively close to the upper sash, so that they do not project into the path of the lower sash, for obvious reasons.

The cam members being reversely ar ranged, the cam-surfaces 37 bear against the stops 27 or 28 in position to hold the sashes from downward movement, but do not prevent them from moving upwardly, while the cam-surfaces 38 prevent upward movement,

but do not prevent downward movement.

By this means the sashes are firmly locked from movement in both directions and can be released for movement in either direction by operating one of the arms only.

It will be noted also that the cam members are so arranged that the releasing movement is always in the direction of the movement of the sash, so that the arms 55 41 serve as lifting members and obviate the necessity for the employment of separate lifting-clips upon the sashes.

When employed upon the larger sizes of sashes or upon sashes disposed at high points and requiring rods having lateral studs to move the sash, such studs may be applied to the arms 55 41, as will be obvious, and the necessity for providing the usual sockets in the sashes obviated.

In Figs. 6 and 7 a modified construction of the device is shown, consisting in forming the frame or casing of cast metal, as at 42,and with the cam members also of cast metal, as at 43 44, and with the arms 55 41 replaced by finger-grips 45 46, the latter substantially fiush with the surface of the casing and the casing provided with pockets or recesses at 47 48 to receive the fingers of the operator or the spur upon the operating-rod.

The modified construction shown in Figs.

6 and 7 is also provided with a spring 49, similar to the spring 40 and coiled around the shafts 50 51, upon which the cam members swing and with the ends bearing against the inner walls of the cam members and maintaining them yieldably in distended position. In the modified construction a tongue 52 is formed upon the frame corresponding to the part released by the cleft 12 in the sheetmetal construction, and the grip members 45 46 in the modified construction are provided with curved lips 53 54, movable beneath the tongue and serving to close the gaps which would otherwise occur between the tongue and the finger-grips.

If preferred, the casing for the cams may be formed relatively narrow, as shown at 56 in Fig. 8, and with the arms 41 extendingover finger-cavities 57 58 in the sash.

Having thus described the invention, what is claimed is 1. In a sash lock and holder, a casing adapted to be embedded in the sash rear wardly of the window-stop, two cams operating in said casing transversely of the sash bearing against said stop, said cams reversely arranged and movable toward each other to effect their release, and means for independently actuating said cams.

2. The combination with a window-frame and its stop and the sash movable relative thereto, of a combined locking and holding mechanism connected to the sash rearwardly of said stop and operative transversely of the sash and against the stop, and. means for releasing said locking and holding means.

3. 'i he combination with a windowdrame and its stop and the sash movable relative thereto, of two cams movablydisposed in said sash, and reversely arranged and movable toward each other to effect their release and operating against saia stop and rearwardly of the same, and means for independently operating said cams.

4. In a sash lock and holder, two locking members each with spaced sides and connected by a transverse web, one of? the sides of each member terminating in a cam-face for bearing against a stationary portion of the window-frame and the other of said sides terminating respectively in operating-arms.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two witnesses.
